AFAIK, unless you are actually using etherstubs, there is no "virtual
switch" in the strict sense-- there's just a pathway out of one
virtualized TCP/IP stack in the kernel (the one for the KVM vnic) and
into another (fugu0).  I'm not sure it's any different if the
destination address is over a hardware interface as opposed to a vnic,
but it seems simpler to my eyes.  I am not a kernel engineer though.
